I was at my sister's near Ely, Minnesota and 7 miles south of Canada.
Nothing that special, but pretty typical for the area:
Much of the habitat is basalt outcrops, sometimes with a complete canopy, sometimes not. Somehow this White pine escaped the clear cut logging that swept through the area about 90 years ago.
Typical fracturing of the lichen civered basalt
Cladonia sp. (Reindeer moss) and Aquilegia canadensis spent seed pod
Antennaria parlinii subsp. fallax and another Antennaria sp. only 10 ft. away.
Campanula rotundifolia (Harebell) and habitat. In the center of the second photo is a white one. The first wild one I have ever seen.
